    Advanced morphological galaxy classification: a comparison of observed and simulated galaxies 
    Hambleton, K. M.; Gibson, Brad K.; Brook, C. B.; Stinson, G. S.; Conselice, C. J.; Bailin, J.; Couchman, H.; Wadsley, J. (Royal Astronomical SocietyOxford University Press, 2011)
    Encoded within the morphological structure of galaxies are clues related to their formation and evolutionary history. Recent advances pertaining to the statistics of galaxy morphology include sophisticated measures of ...

    The cold gas content of bulgeless dwarf galaxies 
    Pilkington, K.; Gibson, Brad K.; Calura, F.; Brooks, A. M.; Mayer, L.; Brook, C. B.; Stinson, G. S.; Thacker, Robert John, 1970-; Few, C. G.; Cunnama, D. (Wiley-Blackwell, 2011-11)
    We present an analysis of the neutral hydrogen (H I) properties of a fully cosmological hydrodynamical dwarf galaxy, run with varying simulation parameters. As reported by Governato et al., the high-resolution, high star ...

    The distribution of metals in cosmological hydrodynamical simulations of dwarf disc galaxies 
    Pilkington, K.; Gibson, Brad K.; Brook, C. B.; Calura, F.; Stinson, G. S.; Thacker, Robert John, 1970-; Michel-Dansac, L.; Bailin, J.; Couchman, H. M. P.; Wadsley, J. (Oxford University Press, 2012-09)
    We examine the chemical properties of five cosmological hydrodynamical simulations of an M33-like disc galaxy which have been shown previously to be consistent with the morphological characteristics and bulk scaling relations ...

    Halo expansion in cosmological hydro simulations: toward a baryonic solution of the cusp/core problem in massive spirals 
    Gibson, Brad K.; Maccio, A. V.; Stinson, G.; Brook, C. B.; Wadsley, J.; Couchman, H. M. P.; Shen, S.; Quinn, T. (American Astronomical SocietyIOP Publishing, 2012-01-01)
    A clear prediction of the cold dark matter (CDM) model is the existence of cuspy dark matter halo density profiles on all mass scales. This is not in agreement with the observed rotation curves of spiral galaxies, challenging ...

    The halo shape and evolution of polar disc galaxies 
    Snaith, O. N.; Gibson, Brad K.; Brook, C. B.; Knebe, A.; Thacker, Robert John, 1970-; Quinn, T. R.; Governato, F.; Tissera, P. B. (Oxford University Press, 2012-09)
    We examine the properties and evolution of a simulated polar disc galaxy. This galaxy is composed of two orthogonal discs, one of which contains old stars (old stellar disc) and the other both younger stars and cold gas ...

    Hierarchical formation of bulgeless galaxies – II. Redistribution of angular momentum via galactic fountains 
    Gibson, Brad K.; Brook, C. B.; Stinson, G.; Roskar, R.; Wadsley, J.; Quinn, T. (Oxford University Press, 2012-01)
    Within a fully cosmological hydrodynamical simulation, we form a galaxy which rotates at 140 km s[superscript −1], and it is characterized by two loose spiral arms and a bar, indicative of a Hubble-type SBc/d galaxy. We ...

    MaGICC baryon cycle: the enrichment history of simulated disc galaxies 
    Brook, C. B.; Stinson, G.; Gibson, Brad K.; Shen, S.; Maccio, A. V.; Obreja, A.; Wadsley, J.; Quinn, T. (Oxford University Press, 2014-10-01)
    Using cosmological galaxy formation simulations from the MaGICC (Making Galaxies in a Cosmological Context) project, spanning stellar mass from ∼107 to 3 × 1010 M☉, we trace the ...

    The main sequence and the fundamental metallicity relation in MaGICC Galaxies: evolution and scatter 
    Obreja, A.; Brook, C. B.; Stinson, G.; Dominguez-Tenreiro, R.; Gibson, Brad K.; Silva, L.; Granato, G. L. (Oxford University Press, 2014-08-01)
    Using cosmological galaxy simulations from the MaGICC project, we study the evolution of the stellar masses, star formation rates and gas-phase abundances of star-forming galaxies. We derive the stellar masses and star ...

    Properties of simulated Milky Way-mass galaxies in loose group and field environments 
    Few, C. G.; Gibson, Brad K.; Courty, S.; Michel-Dansac, L.; Brook, C. B.; Stinson, G. S. (EDP Sciences, 2012-11)
    Aims. We test the validity of comparing simulated field disk galaxies with the empirical properties of systems situated within environments more comparable to loose groups, including the Milky Way’s Local Group. Methods. ...

    The role of feedback in shaping the structure of the interstellar medium 
    Walker, A. P.; Gibson, Brad K.; Pilkington, K.; Brook, C. B.; Dutta, P.; Stanimirovic, S.; Stinson, G. S.; Bailin, J. (Oxford University Press, 2014-06)
    We present an analysis of the role of feedback in shaping the neutral hydrogen (H I) content of simulated disc galaxies. For our analysis, we have used two realizations of two separate Milky Way-like (∼L★) discs – ...

    The stellar metallicity distribution of disc galaxies and bulges in cosmological simulations 
    Gibson, Brad K.; Calura, F.; Michel-Dansac, L.; Stinson, G. S.; Dotter, A.; Pilkington, K.; House, E. L.; Brook, C. B.; Few, C. G.; Cignoni, M. (Royal Astronomical Society, 2012-12)
    By means of high-resolution cosmological hydrodynamical simulations of Milky Way (MW) like disc galaxies, we conduct an analysis of the associated stellar metallicity distribution functions (MDFs). After undertaking a ...

    Thin disc, thick disc and halo in a simulated galaxy 
    Gibson, Brad K.; Brook, C. B.; Stinson, G. S.; Kawata, D.; House, E. L.; Miranda, M. S.; Maccio, A. V.; Pilkington, K.; Roskar, R.; Wadsley, J. (Royal Astronomical Society, 2012-10)
    Within a cosmological hydrodynamical simulation, we form a disc galaxy with subcomponents which can be assigned to a thin stellar disc, thick disc and a low-mass stellar halo via a chemical decomposition. The thin- and ...
